Filed June 20, 1963, Ser. No. 289,303 7 Claims. (Cl. 126-4) Thisinvention relates to apparatus for modifying the temperature of abuilding and to equipment associated with such apparatus and utilizedadditionally in the preparation of food for human consumption.

The invention relates particularly to a stove or heater which may beused as a space heater in a building or may be located within afireplace opening and such heater may have an adjustable removable grillfor use in the preparation of food when desired.

Heretofore, space heaters of many kinds have been provided for modifyingthe temperature of a building and these heaters have utilized wood,coal, charcoal, peat or other fuel which can be burned and which giveoff suflicient radiant energy to heat the space within the building.Other heaters such as hibachis, braziers, etc. have been utilized forthe preparation of food within the building and usually utilize charcoalas a fuel. The space heaters have been bulky, ungainly, occupiedvaluable floor space and were inefficient while the hibachi and brazierhave not been vented to the outside of the building and were an everpresent fire hazard since they were capable of being upset easily.

It is an object of the invention to overcome the difliculties enumeratedand to provide a simple, eflicient space heater which will add to theaesthetic value of the building while serving to provide heat for thebuilding as well as for the preparation of food.

Another object of the invention is to provide temperature modifyingapparatus which can be received within a fireplace opening and will notoccupy valuable floor space.

A further object of the invention is to provide a stove having a grillwhich is adjustable toward and from the fire or heat producing materialand which can be moved into and out of the stove at will.

A still further object of the invention is to provide a stove having adraft opening in either the top or the rear of the stove and a singledamper control adaptable to either.

Other objects and advantages of the invention will be apparent from thefollowing description taken in conjunction with the accompanyingdrawings in which:

FIG. 1 is a perspective illustrating the stove of the present invention;

FIG. 2, an enlarged vertical section thereof;

FIG. 3, a horizontal section on the line 3-3 of FIG. 2;

FIG. 4, an enlarged fragmentary section of the upper portion of thestove and illustrating the damper control;

FIG. 5, a further enlarged section taken along the line 5-5 of FIG. 4;

FIG. 6, an enlarged fragmentary detail perspective of the grilladjusting means;

FIG. 7, a section taken along the line 7--7 of FIG. 6;

FIG. 8, an enlarged perspective of the grate;

FIG. 9, an enlarged section of the draft control taken along the line 99of FIG. 1; and

FIG. 10, a vertical section taken along the line 10-10 of FIG. 9.

Briefly stated the present invention is a space heater or stove of asize and construction to be received within the fireplace opening of abuilding and having a draft opening in either the top or the rearthereof with a damper selectively located in one of such openings and acover plate over the other opening. A single damper control is providedwhich is connectable to such damper regardless of which opening it isin. A grill for the preparation of food is provided within the stove andis adjustable toward and from the fire and swingable into and out of thestove when desired.

With continued reference to the drawings, a stove or housing 10 isprovided having a combustion chamber defined by a hearth plate or bottom11 supported on feet 12, a top 13, side walls 14 and a rear wall 15. Theside walls 14 diverge outwardly from the rear to the front of the stoveand each wall terminates in an outwardly disposed portion 16 having arearwardly disposed flange 17. The upper portion of the front of thestove is covered by a plate 18 and the lower portion of the front may beopened or closed selectively by a pair of folding doors 19. Such doorsare pivotally mounted on hinge members 20 fixed to the outwardlydisposed portions 16. Each door includes inner and outer panels 21 and22, respectively, connected by a hinge pin 23 along their abuttingedges.

In order to control the draft when the doors are closed, the innerpanels 21 each have an opening 24 and an elongated slot 25 locatedadjacent to the lowermost portion thereof. A draft plate 26, slidablymounted in opposed brackets 27, is located on the rear of each innerpanel 21 and is provided with an operating lever 28 disposed within theslot 25. The plate 26 is of a size to completely cover the opening 24when the lever 28 is at one end of the slot 25 and to fully expose suchopening when the lever is moved to the opposite end of the slot.

The lower portion of the rear wall 15 is provided with a plurality ofcorrugations 30 in the area of maximum heat to reduce the amount of heatshock due to the expansion and contraction of the wide expanse of metalwhen subjected to heat. The upper portion of the corrugations terminatein an inwardly disposed flange 31 on which one end of a baffle 32 ismounted and such baflle extends upwardly to the bottom of the plate 18.An opening 33 is disposed in the front portion of the baflle to permitsmoke and other products of combustion to pass upwardly into a chamber34 in the upper portion of the stove.

In order to discharge the smoke and other products of combustion fromthe chamber 34 the top 13 is provided with an opening 35 adjacent to therear of the stove and the rear wall 15 is provided with an opening 36adjacent to the top of the stove. One of the openings is covered by animperforate plate 37 and the other opening is covered by a plate 38 towhich a collar 39 is attached and such collar is adapted to receive aflue connection not shown which is in communication with the exterior ofthe building. A damper plate 40 is pivotally mounted within the collar39 by means of pins 41. An outwardly projecting lug 42 is mounted on thedamper plate 40 in a position intermediate the pivot pins and adjacentto the edge of the plate and such lug is adapted to be pivotallyconnected by a pin 43 to one of a pair of arms 44 and 45 rigidlyconnected to a damper control rod 46. The arms 44 and 45 are located ina position whereby one of the arms will be connected to the lug 42 whenthe damper is mounted in the opening 35 and the other arm will beconnected to the lug 42 when the damper is in the opening 36. Thecontrol rod 46 extends through the front plate 18 and receives anoperating knob 47 mounted on the free end thereof for controlling theposition of the damper plate 40 from a remote position. The plates 37and 38 are interchangeable so that the flue can be connected either tothe top of the stove or the rear of the stove.

An adjustable grate or basket 49 is provided and includes a base 50mounted on legs 51, a pair of side members 52 and 53, and a pair of endmembers 54 and 55. The side members are each provided with a pluralityof slots 56 which permit the passage of air and in which hook members 57on the end of each of the end members 54 and 55 are adapted to bereceived. When the grate is being assembled the hook members 57 areplacedin the selected slots 56 after which the side members 52 and 53are connected to the base 50 by fasteners 58.

In order to provide an adjustable grill for the preparation of food andthe like one or both of the inner side walls 14 is provided with a pairof spaced vertically disposed lugs or gudgeons 60 projecting outwardlytherefrom and each of such lugs has an opening 61 for receiving adownwardly curved portion of a pivot pin or pintle 62. The pintles 62are welded or otherwise fixed to a rack 63 having a plurality of teeth64 projecting outwardly therefrom on the side opposite the pintles. Anarm 65 having an opening 66 at one end for receiving the rack 63 isprovided and such arm has a recess 67 at the opposite end in which agrill 68 is attached by fasteners 69. To control the angularity andposition of the grill relative to the grate an adjusting arm 70 isconnected to the arm 65 by a fastener 71 which passes through an opening72 in the arm 65 and through a slot 73 in the adjusting arm 70.

The grill is supported by the free end of the arm 65 engaging the rearof the rack 63 and by the free end of the adjusting arm 70 engaging oneof the teeth 64. The position of the grill may be varied merely bytilting the grill so that the adjusting arm 70 is no longer inengagement with the teeth and thereafter sliding the arm 65 up or downthe rack to the desired position and again placing the free end of theadjusting arm 70 in engagement with one of the teeth 64. When it isdesired to remove the grill and the food thereon from the stove this canbe done merely by applying a pulling force on the grill 68 to pivot suchgrill outwardly about the pintles 62 and exposing the food thereon.

In the operation of the device the adjustable grate is assembled for anydesired size of fire after which combustible material may be placedwithin the grate and brought to a kindling temperature so that thematerial will burn and modify the temperature within a building. Theamount of heat given off as well as the length of time required to burnthe material can be controlled by the relative positions of the damperplate 40 as well as by the opening or closing of the doors 19 and thedraft plates 26 therein. When it is desired to use the stove for thepreparation of food the pintles 62 may be placed within the gudgeons 60and the grill can be located at any desired height above the fire andthereafter the grill is movable into and out of the stove at will.

It will be apparent that a relatively simple stove is provided which isan eflicient space heater and which can be utilized in the preparationof food for human consun'ltption by the application of an adjustableremovable gril It will be obvious to one skilled in the art that variouschanges may be made in the invention without departing from the spiritand scope thereof and therefore the invention is not limited by thatwhich is illustrated in the drawings and described in the specification,but only as indicated in the accompanying claims.
